openEuler 20.03 LTS SP3 update for curl

1) Missing Encryption of Sensitive Data

EUVDB-ID: #VU83899

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-46219

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error when handling HSTS long file names. When saving HSTS data to an excessively long file name, curl can end up removing all contents from the file, making subsequent requests using that file unaware of the HSTS status they should otherwise use. As a result, a remote attacker can perform MitM attack.

Mitigation

Install updates from vendor's repository.
